320Programing Operations

320.1Going Off-Line from Keyset 1

ON/OFF is lit

Keyset 1 is “Off-Line”

320.2Selecting a Memory Block

1.To select a memory block, depress the appropriate DSS button on Keyset 1 while in off-line status. To simplify

programming of system data, use the programmir %

overlays provided with each ES-6-1 KSU.

Note: Taking Keyset I off-line removes that keyset from service. The rest of the Electra-616 system continues to work. If Station I is the Attendant Keyset. it may be desirable to enter night mode to provide ringing while keyset I is off-line. This depends on the in- stallation

320.3Selecting Addresses Using the Dial Pad

After selecting the memory block, the first address desired must be entered by using the dial pad. After dialing

*1 or 2 digits (dialing a 0 first is not required for addresses numbering less than 10) the display will show the address selected. If programming deals with consecutive addresses there is no need to redial as addresses are automatically in- creased by 1 after writing data into memory. Manual opera- tion of function buttons also allows increasing or decreasing the address by increments of 1. Redialing to change an address is possible at anytime.

320.4Entering Data

1.To enter data the CO/PBX, MIC and DND buttons are used. The LED’s associated with each of these buttons show the status of the datum corresponding to those buttons. When an address is in “clear” mode, no LED is lit.

2.The method of entry using the CO/PBX, MIC and DND vary from address to address. Sometimes they are used singly as for a yes/no choice, sometimes in groups to write numbers in binary. The programming sheets for the different features show how to enter data for each individual address under consideration.

Please note that buttons 7 and 8 are the MIC and DND buttons. In the programming instructions, they will be referred to as buttons 7 and 8.

320.5Use of Function Buttons in Programming

1.Last NBR Button

The Last NBR button is used to perform a clear. When a data button is depressed and its LED is lit depressing the data button will change this status; the Last NBR button will clear the entire address (up to 8 data buttons) which can then be reprogrammed. The Last NRB button will only clear that single address except when Keyset 1 is engaged in programming Memory

Block 5.

2.The HOLD or ADD-ON button depressed once after dialing an address will cause the contents of that address to be displayed: immediately after dialing an address one of these buttons must be depressed. Each sub- sequent depression of the HOLD button will decrease the address by 1 and display the contents of that new address. Each subsequent depression of the ADD-ON button will increase the address by 1 and display the contents of that new address. Only the first use of either button after dialing an address will display that

address without changing it.
